gmp

问题 I cannot install gmpy (1 or 2) on OS X Mountain Lion without warnings. I tried pip , I tried compiling, I installed gcc 4.2.1 and tried to compile gmp with i386 arch (though my Mac is 64bit), none of them are working! The thing is I can setup gmpy with Python 3+ without warnings but not with Python 2.7. The verbose I get when I use: python setup.py install for gmpy2 is: running install running build running build_ext building 'gmpy2' extension creating build/temp.macosx-10.6-intel-2.7

I am trying to build GMP for iOS and i got this configure from someone: ./configure CC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2"

问题 It seems that GMP provides only string serialization of the mpf (floating point) type: mpf_get_str() , mpf_class::get_str() The mpz (integer) type has an additional interface for raw bytes: mpz_out_raw() http://gmplib.org/manual/Function-Index.html Am I missing something? Does anyone know of another library that can serialize GMP floats? Does anyone know of another bignum lib that offers robust serialization? Edit: I'd be happy with serializing MPFR's mpfr_t, as well, which similarly only

I run this command :- ./configure And it gives me this result :- [root@centos-512mb-ams3-01 gmp-4.2.2]# ./configure checking build system type... pentium3-unknown-linux-gnu checking host system type... pentium3-unknown-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE

问题 I'm new for the c++ programming. I installed OpenSSL for my visual studio. I would like to install GMP for visual studio. How should I do that? There is no file such as gmp.exe. I dont know how to install this. Any help would be appreciated. 回答1: It isn't that hard to install GMP on windows. First, download the GMP tar file. You have to install cygwin on windows with gcc, make and m4. You can then run linux command using cygwin. Decompress the tar file, then (RECOMMEND to check out the

问题 To start, I'm running Ubuntu 12.04 32-bit. This program does RSA pub key crypto by taking cin into a char buffer. Then, when I call my encrypt function, I get the following error: GNU MP: Cannot allocate memory (size=1307836444) Aborted (core dumped) When I change the bit-size of the p,q keys I generate, the size in this run-time error increases. This error happens only after I call encrypt() . void generate_pq(mpz_t p, mpz_t q); void compute_n(mpz_t n, const mpz_t p, const mpz_t q); void

问题 EDIT: I'm using Win 10 and Ubuntu from the app store I have tried to install gmpy2 by using: apt-get install libgmp-dev apt-get install libmpfr-dev apt-get install libmpc-dev and also downloaded MPIR and compiled it. however using pip install gmpy2 still gives me the error c:\users\gypsyzz\appdata\local\temp\pip-install-l2hlf7q4\gmpy2\src\gmpy.h(104): fatal error C1083: Cannot open include file: 'mpir.h': No such file or directory error: command 'C:\\Program Files (x86)\\Microsoft Visual

问题 So I've been trying to enable gmp on my macbook pro, but upto no avail. Here's what I've done till now. Uncommented extension=php_gmp.dll in /private/etc/php.ini Uncommented extension=php_gmp.dll in /usr/local/php5/lib/php.ini (coonfiguration file as displayed in phpinfo() ) phpinfo() says gmp is enabled, but when I do php -m , it doesnt shows gmp. What must I do? 回答1: The lines that you're uncommenting are examples. The extension is not actually present on your system -- you need to install
